Origin 2015 and older versions

int ocmath_reducexy_fixing_increbin(const double * px, const double * pData, const UINT nSize, const int iOption, double * pMerged, double dInc);

Parameters

px

[input] pointer to x coordinates of the data

pData

[input] pointer to y coordinates of the data

nSize

[input] the number of the data points

iOption

[input] the way to pick the data value of the output data point, into which a group of data points are merged.

pMerged

[output] pointer to buffer to store the reduced data

dInc

[input] the X Increment to make bins as to create groups

dStart

[input] the start of x coordinates of the data(for subgroup using)

dEnd

[input] the end of x coordinates of the data(for subgroup using)

pnMergedIndex

[output] pointer to buffer to store the index of reduced data in source data

dwCntrl

[input] additional control, can be

REDUCE_XY_CNTRL_EXCLUDE_MISSING_VALUE

Return

Return the number of points in pMerged, return minus value on failure.
